The testo 625 thermohygrometer comes into its own in all situations where the right indoor climate is crucial, for example in archives, storerooms, greeenhouses and buildings. The testo 625 also calculates the dew point and wet bulb temperature quickly and accurately.

With the Testo Smart Probes VAC set, you can check air velocities, humidity, volume flows and temperatures in, on and around air conditioning systems. The robust testo Smart Case enables the measuring instruments to be conveniently transported and ensures that they are always to hand when needed.

The testo 606-2 moisture meter allows you to measure the moisture content in wood and building materials – and the surrounding environment too. This means that you are now also able to check storage and drying conditions quickly and easily.

The compact testo 605i temperature and humidity measuring instrument features professional measuring technology in an intelligent format: it can be used in conjunction with a smartphone/tablet and the testo Smart Probes App to reliably measure air temperature and humidity in rooms and ducts.

The testo 622 thermo hygrometer and barometer is designed to provide you with an at-a-glance look at the air temperature, relative humidity and air pressure. Ideal for monitoring the ambient air, especially in laboratories during calibration or when running experimental setups.

The testo 605-H1 thermohygrometer enables reliable measurement of humidity and air temperature and calculation of the dew point. It has a permanently mounted probe shaft which means it is excellent when it comes to carrying out check measurements in ventilation ducts.

The testo 635-2 temperature and moisture meter allows you to carry out temperature and moisture measurements on a variety of different materials, surfaces and environments. This is made possible due to leading-edge technology and a wide selection of optionally available sensors.

Optionally available sensors for moisture, temperature, pressure dew point and absolute pressure measurements

2 plug-in sensors and 3 wireless sensors can be connected

Super-size memory for up to 10 000 readings

USB cable and PC software for archiving and logging measuring data included

The testo 635-1 temperature and humidity measuring instrument enables you to measure the temperature, air humidity and dew point – in compressed air as well. State-of-the-art technology and a large selection of probes, which are available as an option, enable this wide variety of measuring possibilities.

Probes available as an option mean you can measure air humidity, temperature, absolute pressure and dew point in compressed air

The elegantly designed testo 623 thermohygrometer provides you with a quick and convenient means of measuring the temperature and humidity in offices, living spaces and commercial premises and logs the readings over a period of 90 days.

Measures the temperature and humidity in the room and alerts the room’s occupants when thresholds are reached

Large, easy-to-read display: shows the current reading and provides you with an at-a-glance 90-day statistic snapshot

Non-contact temperature and moisture measurements – with only one device. The testo 835-H1 infrared thermometer not only measures the temperature but has an intergrated moisture sensor that allows you to measure moisture too.

Measure temperature, moisture and dew point with only one device

Calculate the surface moisture content

Easy and comfortable to use: easy-to-follow menu guide, can save up to 200 readings, data analysis with free-to-download software

Four-Point-Laser and 50:1 Optics for precise measurements even over long distances

The U-value is the most important value for proving the heat loss of a building. With the testo 635-2 thermohygrometer and compatible accessories from the U-value set, determining the U-value is now easier than ever.

You can use the testo 435-2 multifunction measuring instrument to carry out all the measurements you need to adjust ventilation and air conditioning systems and assess indoor air quality. You have many optional sensors and probes to choose from which you can attach to the climate measuring instrument. This set already provides you with several probes and with accessories.

Several attachable probes included in the set (vane probes, temperature/humidity probes)

Additional optional probes available for a really wide range of measuring purposes

Kit for carrying out measurements in storage, refrigeration and work rooms, in ventilation ducts and also on refrigeration systems and heat pumps. Keep the testo 440 air velocity and IAQ measuring instrument and the humidity/temperature probe with Bluetooth safely stowed away in the case. So you can get down to work straight away!

Intuitive: clearly structured measurement menu for long-term measurements as well as the parallel determination of humidity and air temperature in storage, refrigerated and work rooms and also in ventilation ducts
